Agenda (all in 25mins) 
   Lync 2010 video capability
   Lync 2013 a standards-based approach
   Lync 2013 video changes
   Scalable Video Codec (SVC)
   Video interoperability
   Changes to video manageability in 2013
   Questions

30/07/2012   Microsoft Unified Communications User Group London (MUCUGL)   3
First some Lync 2010 video
history
 Lync Server 2010 AVMCU is limited to H.263 (P2P only) and
  RTV video codecs
 HD 720p is only possible with RTV and point-to-point (not
  AVMCU)
 Lync Server 2010 needs to be enabled for HD
    Set-CsMediaConfiguration Identity Global -
     MaxVideoRateAllowed Hd720p15M
 HD 720p receive requires either dual core (15fps) or quad
  core (30fps)
 HD 720p both send/receive requires quad core
 Interoperability with legacy video requires Microsoft SIP
  signalling capability and RTV video support (3rd party SW or
  native support)
30/07/2012     Microsoft Unified Communications User Group London (MUCUGL)   4
Lync 2013 a standards-based
approach
 Microsoft engaged in Unified Communications
  Interoperability Forum (UCIF) for standardisation of
  video, transport and signalling
 Lync 2013 H.264 bitstream is likely to confirm to UCIF
  interoperability spec, removing the need to perform
  media transcoding for other UCIF compliant H.264
  systems
 Lync 2013 video specifications disclosed publically
 Capability to leverage H.264 hardware-based
  acceleration
 Polycom H.264 SVC technology adopted
 More on SVC later

     The combination of these two processes result in video appropriate to the
     requesting video endpoint. AVMCU routes/discards video modes that are
                unsuitable for the client based upon SDP discovery

Video Interoperability
 SVC Config Mode 0, 1 (Simulcast)
       Suggestion is Mode 0 for legacy video
        (H.264 AVC or RTVideo)
       Mode 1 for H.264 SVC
   Simultaneous streaming being a
    requirement for non-transcoding MCU
 Lync 2010 and/or legacy video
  endpoints will result in gallery                    Source: MSDN 2.2.12.2 Video Source
  view and high resolution video                      Request (VSR)
  being unavailable
 Video gateways still necessary to
  facilitate Microsoft SIP signalling
 3rd party bridges still a
  requirement for communication
  with standard
  SIP, H.323, ISDN, TIP, etc.

TotalReceiveVideoBitRate      kbps of video, which may consist of multiple 180P video
Kb                            streams or a single 540P video stream.                            : 6000
